About The Position

SAIC is seeking a Model-Based Systems Engineer (MBSE) to support hypersonic programs at Naval Surface Warfare Center (NSWC) Crane. The role is embedded at the customer site and involves working directly with government engineers and program teams on hypersonic development efforts. The engineer applies systems engineering and MBSE methods throughout the system lifecycle, from concept development through validation and verification. The position includes developing and maintaining system architecture models, primarily using Cameo Systems Modeler, and applying SysML or equivalent languages to represent system structure, behavior, requirements, and interfaces. The engineer also supports the program’s transition from document-based to model-based engineering practices, reviews technical data and designs, contributes to technical reviews, and coordinates engineering work with government stakeholders, contractors, subcontractors, and suppliers.

Requirements

Active Secret clearance; Interim Secret is required to start, and the candidate must be able to obtain Top Secret.
Bachelor of Science in an engineering discipline.
MBSE experience, including required experience with Cameo Systems Modeler.
At least 5 years of systems engineering experience.
Demonstrated experience in product design, procurement, or production-floor engineering.
Experience designing prototypes or ensuring designs meet functional requirements from procurement through validation and verification.
Strong understanding of systems engineering processes and methodologies across the program lifecycle.
Excellent written and verbal communication skills, including the ability to produce and present technical documentation.

Nice To Haves

Aerospace, Mechanical, or Electrical Engineering degree.
Familiarity with SysML modeling language.
Experience supporting DoD hypersonic, missile, or advanced weapons programs.
